ToI all 'whom may concer' Be it known that I, RICHARD H. STERLING, a.Citizen of the AUnited States, residing at Vl'vatsonville, in the countyof Senta Cruz and `State of Californie, `have inventedcertein new anduseful Improvements in Long-Dis tence Roer 'ding Indicators forReciprocating Devices, oi liich the following is a specil'ies tion.

The olijcot of' the present invention is to provide e longr distancerecording indicator for ges holders, reservoirs, tide end river levelsand the like. Where gas holders, reservoirs, oil tanks', etc., arelocated et distant points, s device to indicate the amounts contained insuch storage pieces is always All electric sell bell is the simplest,lont this only serves as an alarm to tell when. the holder orresort/*oir is either full or empty, und issometimes confusing, 'whenboth high and low oonteot points ere used., on account of the dillieultyof determining whether the bell is ringing for the high or the Theolii/ect or the pres. it iri`fenideen op; :its which willnoi. cversg'fsulJe l itisl change in 'sol 'when either rising or tolling but lreoorfl it on s' sheet olE peper, so that the amount of or other com.nstorage, or the level et the distant points, con be ascertained et' anyhour of the doy.

ilverl consists out Referring to the drawing, l represents a. sprocketwheel on e. shaft 2 carrying e chain 3, one end of the chainbeingsttaehed to a. suitable weight ll, end the` other end beingatt-sched to the holder, l'loet, or other device not shown, thereciprocating motion of Whic i it is required to record. To the end ofthe shaft 2 is rigidly attached it' disk 5 having lourfprojecting pinsplaced at e ual distances from each other. As the spreel et shalt slowlyrevolves, owing to the motion of the floot orgas holder,l one ofthe pins6 cornes in Contact with a square projecting pin 8 on o crank 9fastened' to en armature shalt 10, and thereby saidcreuk 9 is itselfcarried in the seine direction of rotation as the disk, but revolving soslowly generates no perceptible liow of current in the erme-l ture andwill not e'llect the miniatureA of the recording instrument hereafter tobe described. Seid armature shelt- 10 is arranged eccentric with thesprocket Wheel shaft 2, so that, the pin 8 'on the ernisture crank notdescribing the seme eircle es the pin 46 on the dish, stt-er melting tquarter of u. revo-v lution the pin escapes from the in 6, and theorenlr is released :rnd is no enger carried ioruurd hy the dish pin.`'Upon being; thus released it is suddenlyreturned to its originelupright position by that one oi tiiio springs ll, which Wes brought intotension by this revolution through a` quarter of s circle. .l heermeture oscillates bee tween permanent lield Amagnets l2, and thereforethis quick action of the armature in 'returning to its ori ine-lposition generates s strong impulse of e estrie current through thearmature and ,through ein electric cir cuit 13. On its return movement,its Inomentum would. carry it pest its original position und quicklyoscillating beck in the first direction agr-iin would generate currentin. the wrong directirgiiz, hut this isv pre* vented lay the abutment olthe `*sin 8 geinst :mother one oi the pins This action is epeeted esiliodisk revolves through eeeh quarter ois revolution, sind in each corn-ldirection when the diskis revolving tothe right und in another directionwhen revolving to lel't, these dillerent directionsof I the currentsbeing; necejjiryto the proper action of the'indieer'for, which wll benow described. The wire of the electric circuit at the other end of theline passes around a'n electro-magnet 14, which 1s thereby energizedand'attracts an armature which is in three parts, a central part revolviloosely upon a shaft 16, and two termina parts .17 hinged to the centralpart, as shownV magnet 21 extending above it, thus producing with theeleetroqnagnet a polarized system.

Attached to the two hinged armature are,pawls' 22 whic respectivelyengage with the teeth of two ratchet wheels 23, which are both rigidlyfastened on the saine shaft 16, but have their teeth arranged in'oposite directions. Therefore, when an impu se of current arrives from thetransmitter, and magnetizes thc two cores of the electromagnet,- sincethe armature itself is permanently magnetized, it becomes se lectiveasto the direction of its swing, and will, of course, be attracted at oneend to the core that is temporarily inagnetized in oppositet'polaritythereto and repelledat the other en thus bringing it into the ositionshown in Fig. 6. Since the 'sma spiral springs 19 are of less tensionthan the springs 20, the hinged terminal portion 17 of the armature at'the attracted end is first drawn' down, bringing this end of thearmature into alinement with the main or central por- .tion thereof, andthis movement swings the pawl 22 into a tooth of the ratchet wheel, andthen the continued movement of the armature advances the ratchet wheelthe space of one tooth. On the interruption of t e current the armatureassumes itsnormal osition. Should the current 'be received trom thetransmitter in the opposite direction, due to an opposite direction ofrotation of its armature, then the armature of the receiver would swingin the opposite direction and cause a partial rotationi of the ratchetwheels also in the opposite d"'rection. Uglon the shaft 16 is secured api ion 25, Whic by the rocking of the shaft inA one direction or theother in the manner above explained, im arts a reciprocating movement toa rack 26, which carries a en 27, the movement of which penis recor edin a lcurved or irregular line upon a sheet of paper 28 caused to travelat a regular rate by a clock work mechanism 29.
